What is the hypotenuse angle theorem?

Answer 1

The hypotenuse angle theorem, also known as the HA theorem, states that 'if the hypotenuse and an acute angle of one right triangle are congruent to the hypotenuse and an acute angle of another right triangle, then the two triangles are congruent.'

Answer 2

If two right triangles have

(hypotenuse and an acute angle of one) = (hypotenuse and the corresponding angle of the other)

then the triangles are congruent
